MULTI-POINTER FOR TOUCHSCREEN STYLUS
The present invention discloses a multi-pointer touchscreen stylus, which comprises a shaft having at least two pointers at the front end thereof. The present invention can present personal calligraphy according to one's handwriting. The present invention can also present a stroke with varying widths according to varying strengths of writing action, whereby the user may write on a touchscreen with more pleasure. Further, the present invention can prevent a touchscreen from being stained or scratched.
1. Field of the Invention
The present invention relates to a touchscreen stylus, particularly to a multi-pointer touchscreen stylus able to present one's calligraphy.
2. Description of the Related Art
It is convenient to operate a touchscreen with one's finger. However, the finger is easy to sweat and likely to leave stains on the touchscreen. Therefore, a touchscreen is usually operated with a stylus. The touchscreen styluses may be categorized into the resistive touchscreen stylus and the capacitive touchscreen stylus. In a resistive touchscreen, an upper ITO (Indium Tin Oxide) controller and a lower ITO controller are used to detect the voltage variation of the touchscreen, whereby to determine the coordinates of the contacted point. Therefore, the resistive touchscreen stylus is simply a pen-like object used to press a resistive touchscreen. In a capacitive touchscreen, the human body's static electricity induces the capacitance variation of the arrayed transparent electrodes, and the capacitance variation is used to determine the coordinates of the contacted point.

Accordingly, the present invention proposes a multi-pointer touchscreen stylus to overcome the abovementioned problem.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a multi-pointer touchscreen stylus, which can present the features of one's handwriting according to the strengths of one's writing actions.
Another objective of the present invention is to provide a multi-pointer touchscreen stylus, whereby to prevent the touchscreen from being stained by sweat or being scratched by a stylus or finger.
A further objective of the present invention is to provide a multi-pointer touchscreen stylus, which can function like a brush pen to present Chinese calligraphy on the touchscreen.
To achieve the abovementioned objectives, the present invention proposes a multi-pointer touchscreen stylus, which comprises a shaft having at least two pointers at the front end thereof.
Below, the embodiments are described in detail in cooperation with the attached drawings to make easily understood the structural features and efficacies of the present invention.
The present invention discloses a multi-pointer touchscreen stylus, which applies to a resistive or capacitive touchscreen, and which can present the features of personal calligraphy.

In the present invention, different types of pointers generate different textures of calligraphy. For an example, the multi-pointer touchscreen stylus 20 having three spherical pointers 262 (shown in
For another example, the multi-pointer touchscreen stylus 20 having brush-pen tip pointers 264 (shown in
For a further example, the multi-pointer touchscreen stylus 20 having one nib 28 and several pointers 26 fabricated into a one-piece component (shown in
In conclusion, the present invention can prevent a touchscreen from being stained by dirt and sweat and from being scratched by improper operation. Further, the present invention can present personal calligraphy according to personal writing action. Thus, handwriting on a touchscreen becomes more vivid. Besides, the multi-pointer touchscreen stylus of the present invention is applicable to various resistive and capacitive touchscreens.
The embodiments described above are only to exemplify the present invention but not to limit the scope of the present invention. Any equivalent modification or variation according to the spirit of the present invention is to be also included within the scope of the present invention.
